,To all whom it may cof/warn This 'Invention relates to improvements in` railway signal usees.

The present invention pertains to an improvement in the manner o connecting to one end of the tube a spike by which the usee may be supported in an upright position by driving the spike either in the ground, road-bed or railroad tie in a manner well known to those acquainted with the use of railway signal fusees.

Heretofore spikes have been attached to or made a part of a plug, sometimes wood and sometimes metal, and this plug is made of a size to fit the end of the fusee and is glued therein. Where ythe plug or means of attaching the spike is within the open end of the fusee tube, it is liable to become detached, and the primary object of my present invention is to attach the spike to a crimped end closure which is a part of the tube itself so that it is not possible for the spike to become lost or detached from the tube, nor is it possible for the end of the tube to become open, and the compound therein permitted to-sift out of the tube in transportation, which latter would be the case where a plug is inserted in the 1 open end of the tube and becomes detached therefrom,

In the accompanying drawings :-Figure y 1 is a perspective view of the spike end o a fusee tube with one form of my improvenient afpplied thereto. Fig. 2 is a sectional view dat Fig. l. Figs. 3, 4, 5, 6, 7, 8, '9, and 1li-'each show modified forms or con strnctions which embody my present improvement, Fig. ll is an enlarged top view c" the' clamping washer shown in Figs. 1`

and 2.,

in carrying out my improvement, I provide the paper or fiber fusee tube l with a crimped closed end 2 which closed end is an integral part of the tube itself.

Referring now particularly to the form shown in Figs. l and Q', tlie'nail or spike 3 is provided with a suitably enlarged head a Y Specification of vLetters Patent. Application filed May 5, 1914. Serial No. 836,581,

The stem of the spike passes through the crimped closure 2 of the tube so that the head i's on the inside o'f the tube. The clamping washer 5 is then passed over the stem of the spike and forced downward against the outer side of the closure 2 thus clamping the closure irmly between the head land the washer 5 and irmlyclamping the spike to theclosed end of` the fusee tube. The form of washer shown in Figs. 1 and 2 and l1 is slightly dished outwardly as shown and has its opening 5, formed with lateral recesses 5b, which-lierre between the recesses prongs or arms 5c. rllhe'se arms are forced in frietional engagement with the stem ot the spike either by pressing the dished washer inward at its center which will cause the arms 5c to grip the stem of the spike 3, or the ends of the arms may be swaged so as to grip the step of the spike, spike end of the tusee', a separate cement or iron plug 6 ma be placed within the tube and between tile head L of the' spike and the burning composition 7, -and this wei 'ht may be used in connection with any of t e forms herein shown. When it is not desired to weight the spike end of the fusee, the lplug 6 will be omitted and then the burning` composition 7 is packed directly agalinst and in contact with the head of the sp1 ve. f

In Fig. 3 the construction is slightly modiiied in that the head i of th'e spike 3 is slightly cup-shaped and the washer 8 forces the closure 2 down into this cupsliaped head as shown, thus making a bent portion of the closure,' making a sort ot' a lockin this instance, the Washer una'y have an opening without any lateral recesses and the washer mayv be made to tightly fit the stem of the spike.

Fig. i shows a construction similar to Fig. 3, and in`which a washer 8, like that shown in Fig. 3, is "used but in this instance, the outer surface of the vstem of the spike isI shoulders serve to hold and lock the washer '3 in position.

Fig. 5 shows a construction like that shown in Fig. 4, and differs therefrom only in having' the stem of the spike provided with a tapered portion 3, and the washer Where it is desired to weight the is forced down on this tapered portion so that the washer is wedged and held into position.

Fig. 6 differs from Figs. 1 and 2 in that the head of the spike 4a, vis made coneshaped and the closure 2L correspondingly cone-shaped, and the washer 10 diers only from the washer 5 in that it i made cone or dome-shaped to correspond with the cone or dome shaped closure 2a.' This construction lis used when it is desired to have the closure of the fuse@ of a dome shape.

Fig. 7 shows a modification. in that the stem of the spike is provided with an ntegral' fia-nge 11 that fits against the outer side of the closure 2, and a washer 12 is clamped to the inner side of the closure 2 by sivaging the' projection or end 13 of the spike, which receives the washer thus clamping the closure 2 between the iiange 11 and Vthe Washer. 12.

rig. s Shows a modification intimi the washer 8-is clamped to position by*turning a portion of thespike outward against the washer as shown at 14 and thus serves tov clamp the closure 2 between the Washer 8 andthe head' of they spike.

Figi) is a modiiication 0f Fig. 3 in that the Washer 8 is omitted and the stem of the spike is turned outward into a flange 15,

which clamps the closure 2 between the head i of the spike, and the turned flange 15 of the stem of the spike.

Fig. 10 is a modification inthat the closure 2 is provided with a metallic eyeletA 1G, and the stein of the spike 3 provided with a lflange 17 near its inner end, and the inner end projected through the eyelet and swaged or expanded as shown at 18 to clamp the closure 2 between the iiange 17 and the expanded end 18, the eyelet serving tofurnish a metallic surface against which the lange and expanded end are clamped, the eyelet serving, of course, to strengthen the closure' 2.

From the foregoing, it will be observed that in all the forms here shown the spikeis secured to' the fusee by clamping yit to a crimped closure of the tube which closure is formed as an integral part of the tube.

I wish it understood that While this involition is particularly intended for use in railway time burning fusees, it is capable of, vuse with any tube having a crimped end closure which contains a burning compound y `whether that compound be of the character used in railway time burning signal fu'sees or in fireworks, whenever it is desired to have the tube supported in an upright position while the composition therein is biirn ing, and in fact, it may be applied to Roman candles so that they can be supported in an l y upright position by driving` the spike into the lawn, or vinto a board placed for that purpose. In other words, the inventionl is adapted for use in fireworks 'orn torch which have an end closure.v l l Having thus .describ'edmy invention what I claim and desire to secure by Letters Patent is: A y
